Praxair enhances on-site gases production technologies
Danbury, CT
Praxair has expanded its line of on-site supply systems. Its UHP nitrogen/oxygen plants now have the option of adding a liquefier to provide backup UHP liquid nitrogen, eliminating the need to truck-in additional supplies. The liquefier offers significant efficiencies, according to the company, consuming as little as one-half the power compared to liquid produced through conventional means. UHP hydrogen with less than 10 parts per billion each of typical impurities can now be provided with cost savings of up to 75 percent compared to electrolysis, Praxair claims. — SES
